Genes affected

ZRANB1 (HGNC:18224): (zinc finger RANBP2-type containing 1) Enables K63-linked polyubiquitin modification-dependent protein binding activity and thiol-dependent deubiquitinase. Involved in several processes, including positive regulation of Wnt signaling pathway; protein deubiquitination; and regulation of cell morphogenesis. Located in cytosol and nucleoplasm.

The c.989T>C (p.I330T) alteration is located in exon 2 (coding exon 2) of the ZRANB1 gene. This alteration results from a T to C substitution at nucleotide position 989, causing the isoleucine (I) at amino acid position 330 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
